Hunger-Killing Workouts

Exercising in short bursts has been shown to be quite effective for burning fat. Now it seems that it also promotes eating less. In a study in the journal Obesity, overweight people felt less midafternoon hunger on days when they walked for five minutes every hour rather than for 60 minutes nonstop in the morning. And in a separate study led by Aaron Sim, a researcher at the University of Western Australia, overweight men consumed fewer calories over two days after they did a half-hour interval workout on a stationary bike—alternating 15-second high-intensity surges with 60 seconds of relaxed pedaling—relative to when they cycled at a moderate pace for the same duration (30 minutes). Compared with steady, moderate-intensity workouts, intermittent periods of high-intensity exercise were linked with lower circulating levels of hunger-stimulating hormones.
